摘 要:目的和方法:运用免疫组化技术SP法检测MMP -9、TIMP-1在68例膀胱移行细胞癌中的表达,分析它们与临床病理分级、分期的关系。旨 在探寻它们在膀胱移行细胞癌(TCCB)浸润、转移中的作用。结果:MMP-9在TCCB中高表达, 41/68例阳性,阳性率为60%。MMP-9的表达阳性率随肿瘤分级、分期的升高而增加 (P<0.05)。TIMP-1在TCCB中高表达,31/68例阳性,阳性率为45.5%。TIMP-1的 表达随肿瘤分级、分期的增加而呈下降趋势(P<0.05)。MMP-9在TCCB的表 达与TIMP-1的表达经统计学分析有相关性。MMP-9(+)/TIMP-1(-)表达在浸润性或高分级 肿瘤中则比例较高,差异有统计学意义(P<0.05)。结论:MMP-9和TIMP- 1与TCC B的分级和分期相关,MMP-9及TIMP-1的差异表达对于TCCB的侵袭发展发挥了重要作用。Purpose and Methods:The expression of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 were s tudied by SP immunohistochemistry in 68 cases of transitional cell carcinoma of bladder to investigate the relationship of the expression and clinicopathologica l parameters.Results:The expression of MMP-9 and TIMP-1 were higher in TCCB.The expression rate of MMP-9 was 60% and was elevated with grade and stage.The expre ssion rate of TIMP-1 was 45.5%.There was a inverse relationship between the expr ession rate and grade or stage.It was found that the tumors expressed MMP-9(+)/T IMP-1(-) had higher pathological stage and grade than the groups expressed MMP-9 (-)/TIMP-1(+).Conclusions:The expressions of MMP-9 and TIMP-1 be correlated with grade and stage of TCCB.The increased MMP-9 expression and decreased TIMP-1 exp ression were associated with the invasion and development of TCCB.
